I've got a first cut of the rebase here: git://github.com/gwd/sig-virt-xen out/update-4.4.1-rc1-ee81dda-RFC To build it, you'll need to download the polarssl tarball: http://xenbits.xen.org/xen-extfiles/polarssl-1.1.4-gpl.tgz And you'll need a tarball based on (unfortunately) a private tree, which you can find here: git://github.com/gwd/xen base/update-4.4.1-rc1-ee81dda-RFC This branch is based on upstream ee81dda (the current staging-4.4), with an additional two backported commits. To reproduce the tarball, checkout the above branch, then: ./configure make -C tools qemu-xen-dir-find make -C tools qemu-xen-traditional-find make src-tarball A couple of notes: * I haven't actually had time to test this yet! This is just so we're not totally duplicating work... * This does not have XSA-100 in it yet, so it's not quite ready for release. -George
